266999 divided by 51 
The aim is to understand the frequency of 51 in 266999.

Let's proceed to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 51

Let's proceed to step 2:
When dividing 26 by 51, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 51

On to step 3:
When dividing 266 by 51, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 11 after subtracting 255 from 266.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 51

Step 4:
The number 51 fits into 119 2 times, leaving a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we subtract 102 from 119, we get 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 51

Going ahead to step 5:
51 goes into 179 3 times with a remainder of 26.
The next digit of our result is 3. 
Result so far: 523.0
Subtract 153 from 179 to get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 51

Going ahead to step 6:
269 divided by 51 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5235.0
If we subtract 255 from 269, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
51 can be fit into 140 2 times, resulting in a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 5235.2
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
If we divide 380 by 51, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 5235.27
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
The number 51 fits into 230 4 times, leaving a remainder of 26.
The next digit of our result is 4. 
Result so far: 5235.274
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
When dividing 260 by 51, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5235.2745
Subtract 255 from 260 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5235.2745
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
51 can be fit into 500 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 5235.274509
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 13:
The number 51 fits into 410 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 5235.2745098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
51 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5235.2745098
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 5235.2745098, with a leftover of 2e-08.
